Siemens Marq 21 30A/30A Dual Breaker Feeder - 480V/3P
Dual 30A | 480V/3P | 100A Frame | Independent Circuits
This Siemens Marq 21 30A/30A dual breaker feeder consolidates two independent feeder circuits into a single MCC bucket, engineered for maximum reliability. Rated at 480V with dual 100A frame breakers, it maximizes panel density while maintaining full isolation between circuits. Each breaker operates independently, enabling fast troubleshooting with modular plug-in design. Perfect for HVAC systems, pharmaceutical production, and data center infrastructure, this dual-compartment design cuts installation costs by reducing the total number of bucket slots required. The Marq 21 architecture ensures backward compatibility with existing MCC lineups, enabling seamless capacity upgrades. Meets UL 845 and NEC Article 240/430 standards.
